No problem.

Yes, the source is hosted on a forge at my lab:
http://gforgeigm.univ-mlv.fr/projects/tatoo/

The latest release is pretty old, the current plan is to release version 4
(the next one) in november.
So if you want to use it, I think it's better to use the latest source 
from the repository.
The source respository (SVN) is accessible here:
http://gforgeigm.univ-mlv.fr/scm/viewvc.php/trunk/?root=tatoo

You just need ant to build the project.
To start, the best is to take a look to the sample named calc-ast (in 
samples/calc-ast).

Ok, I will surely propose to use Tatoo as front end to the java compiler 
as a summer  project.
